The practice of municipal wastewater treatment and reuse in the Kingdom of Saudi
Arabia is in urgent need of improvement in all aspects. Major recommendations include
the need to: immediately expand wastewater collection, treatment capacity, and reuse;
establish process selection and design guidelines considering the Kingdom's local
requirements; establish rational and enforceable quality criteria for effluent disposal and
reuse; and start a system of plant inspection and reporting that holds plant operating entities
liable for any violations.
